From the YouTube user’s description of the confrontation, which got physical:

After just singing and worshiping God for a while, Roger decided that we should all hold hands in a circle and continue singing. So we did.

Someone (Actually a person who came up and hugged and kissed some of us who he knew from the past) convinced some people that we were there to protest against the no on 8 campaign.

Then some guy who was dressed up like one of the sisters (The sisters of perpetual indulgence is a group of men who dress up like nuns and call themselves the spiritual authority of the Castro.) took a curtain-type thing (Which I think they use to curse people) and wrapped it around us.

Then a crowd started gathering. We began to sing “Amazing Grace”, and basically sang that song the whole night. (At some points we also sang “Nothing but the Blood of Jesus” and “Oh the Blood of Jesus”.) At first, they just shouted at us, using crude, rude, and foul language and calling us names like “haters” and “bigots”. Since it was a long night, I can’t even begin to remember all of the things that were shouted and/or chanted at us. Then, they started throwing hot coffee, soda and alcohol on us and spitting (and maybe even peeing) on us. Then, a group of guys surrounded us with whistles, and blasted them inches away from our ears continually. Then, they started getting violent and started shoving us. At one point a man tried to steal one of our Bibles. Chrisdene noticed, so she walked up to him and said “Hey, that’s not yours, can you please give it back?”. He responded by hitting her on the head with the Bible, shoving her to the ground, and kicking her. I called the cops, and when they got there, they pulled her out of the circle and asked her if she wanted to press charges. She said “No, tell him I forgive him.”

Afterwards, she didn’t rejoin us in the circle, but she made friends with one of the people in the crowd, and really connected heart to heart. Roger got death threats. As the leader of our group, people looked him in the eyes and said “I am going to kill you.”, and they were serious. A cop heard one of them, and confronted him. (This part is kinda graphic, so you should skip the paragraph if you don’t want to be offended.) It wasn’t long before the violence turned to perversion. They were touching and grabbing me, and trying to shove things in my butt, and even trying to take off my pants – basically trying to molest me. I used one hand to hold my pants up, while I used the other arm to hold one of the girls. The guys huddled around all the girls, and protected them.
